NYSE: DBO

The Fund may invest directly in United States Treasury Obligations. The Fund may also gain exposure to United States Treasury Obligations through investments in exchange-traded funds (“ETFs”) (affiliated or otherwise) that track indexes that measure the performance of United States Treasury Obligations with a maximum remaining maturity of up to 12 months (“T-Bill ETFs”). The Fund holds as collateral United States Treasury Obligations, money market mutual funds and T-Bill ETFs (affiliated or otherwise), if any, for margin and/or cash management purposes. While the Fund’s performance reflects the appreciation or depreciation of those holdings, the Fund’s performance, whether positive or negative, is driven primarily by its strategy of trading futures contracts with the aim of seeking to track the Index.

The Commodity Futures Trading Commission (the “CFTC”) and certain futures exchanges impose position limits on futures contracts that reference the Index Commodity (the “Index Contracts”).

The Managing Owner may determine to invest in other futures contracts if at any time it is impractical, including in scenarios wherein the futures market for an Index Contract is thinly traded, or inefficient to gain full or partial exposure to the Index Commodity through the use of Index Contracts. These other futures contracts may or may not be based on the Index Commodity. When they are not, the Managing Owner may seek to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with an Index Contract.

The Fund offers common units of beneficial interest (the “Shares”) only to certain eligible financial institutions (the “Authorized Participants”) in one or more blocks of 50,000 Shares (“Creation Units”). The Fund commenced investment operations on January 3, 2007. The Fund commenced trading on the American Stock Exchange (which became the NYSE Alternext US LLC) on January 5, 2007 and, since November 25, 2008, has been listed on the NYSE Arca, Inc. (the “NYSE Arca”).

Under no circumstances may any person or entity claim any affiliation with Deutsche Bank without the written permission of Deutsche Bank.

The Index Sponsor may from time to time subcontract the provision of the calculation and other services described below to one or more third parties.

The Index is intended to reflect the economic performance of investing in futures contracts on the crude oil sector. Commodity futures quoted in U.S. Dollars and listed on major U.S. and European exchanges are eligible for inclusion in the Index. The Index Sponsor selects the futures contract with the highest implied roll yield, aiming to maximize the potential roll benefits in backwardated markets and minimize the loss from rolling in contango markets. If two futures contracts have the same implied roll yield, the futures contract with the minimum number of months to the exchange expiry month is selected. “Implied roll yield” is calculated by dividing the closing price of the commodity futures contract which is to be notionally exited by the closing price of the relevant futures contract, raised to the power of one divided by the fraction of the year between the base futures contract and the relevant eligible futures contract, minus one.

On the first Index business day of each month, the futures contract currently included in the Index is tested for continued inclusion in the Index based on its delivery month. If the delivery month for the contract is the next calendar month, a new contract is selected. This takes place between the second and sixth Index business day of the month.

Effective November 10, 2025, the single Index Commodity comprising the Index is Light, Sweet Crude Oil (WTI).

The Index includes provisions for the replacement of futures contracts as they approach maturity. This replacement takes place over a period of time in order to lessen the impact on the market for the futures contracts being replaced. With respect to the Index Commodity, the Fund employs a rule-based approach when it ‘rolls’ from one futures contract to another. Rather than select a new futures contract based on a predetermined schedule (e.g., monthly), each Index Commodity rolls from one contract to another futures contract that is intended to generate the most favorable ‘implied roll yield’ under prevailing market conditions. Where there is an upward-sloping price curve for futures contracts, the implied roll yield is expected to be negative, which is a market condition called “contango”. Contango exists when contract prices are higher in distant delivery months than in nearer delivery months, typically due to costs associated with storing a given physical commodity for a longer period. Rolling in a contangoed market will tend to cause a drag on returns from futures trading. The Index’s selection of a new futures contract on an Index Commodity in such market conditions is designed to minimize the impact of negative roll yield. Additionally, in instances of particular market stress, futures contracts for the month next to occur (e.g., the April 2026 futures contract available in March 2026) may trade significantly lower than futures contracts with delivery in later months, typically indicating an oversupply of the reference commodity, in what is referred to as a “super contango” market. See Part I, Item 1A. “Risk Factors” below for a discussion of the risks associated with a super contango market.

Conversely, where there is a downward-sloping price curve for futures contracts, the implied roll yield is expected to be positive which is a market condition called "backwardation". Backwardation exists when prices are higher for contracts with shorter-term expirations than those with longer-term expirations, a condition that is typically associated with commodities that are consumed quickly instead of being held in storage. Rolling in a backwardated market will tend to enhance returns from futures trading. The Index’s selection of a new futures contract on an Index Commodity in such market conditions is designed to maximize the impact of

2

positive roll yield. The Index takes the impact of implied roll yield into consideration by selecting, as the replacement for an expiring futures contract, from a predetermined set of eligible contracts the futures contract that generates the most favorable implied roll yield under the current market conditions.

Returns from futures trading are called excess returns, which is the combined return based on the spot prices of the Index Commodity and the roll yield from trading Index Contracts.

The Index is calculated in USD on an excess return (unfunded) basis, which means that the Index reflects the return associated with spot prices for the Index Commodity and the roll yield associated with trading Index Contracts. Unlike the Index, the Fund also holds as collateral securities that are expected to generate income, including Treasury Securities, money market mutual funds, and T-Bill ETFs. These securities are held with the Custodian (as defined herein). In addition, Treasury Securities for deposit may be held with the Commodity Broker (as defined herein) as margin for the Fund’s futures positions. The Index does not reflect any corresponding income characteristics.

The futures contract price for the Index Commodity will be the exchange closing price for the Index Commodity on a day on which the appropriate exchange is open for business (an “Index Business Day”). If a weekday is not an Exchange Business Day (as defined in the following sentence) but is an Index Business Day, the exchange closing price from the previous Index Business Day will be used for the Index Commodity. “Exchange Business Day” means, in respect of the Index Commodity, a day that is a trading day for the Index Commodity on the relevant exchange (unless either an Index disruption event or force majeure event has occurred).

On the first Index Business Day of each month (the “Verification Date”), the Index Commodity futures contract will be tested in order to determine whether to continue including it in the Index. If the Index Commodity futures contract requires delivery of the underlying commodity in the next month (the "Delivery Month"), a new Index Commodity futures contract will be selected for inclusion in the Index. For example, if the first Index Business Day is May 1 of the current year, and the Delivery Month of an Index Commodity futures contract currently in the Index is June of the current year, a new Index Commodity futures contract with a later Delivery Month will be selected.

For the underlying Index Commodity in the Index, the new Index Commodity futures contract selected will be the Index Commodity futures contract with the best possible “implied roll yield” based on the closing price for each eligible Index Commodity futures contract. Eligible Index Commodity futures contracts are any Index Commodity futures contracts having a Delivery Month (i) no sooner than the month after the Delivery Month of the Index Contract currently in the Index, and (ii) no later than the thirteenth month after the Verification Date. For example, if the first Index Business Day is May 1 of the current year and the Delivery Month of an Index Contract currently in the Index is June of the current year, the Delivery Month of an eligible new Index Commodity futures contract must be between July of the current year and June of the following year. The implied roll yield is then calculated and the Index Contract with the best possible implied roll yield under the current market conditions is then selected. If two futures contracts have the same implied roll yield, the futures contract with the minimum number of months prior to the Delivery Month is selected.

After the futures contract selection, the monthly roll for the Index Commodity subject to a roll in that particular month unwinds the old commodity futures contract and enters a position in the new commodity futures contract. This takes place between the second and sixth Index Business Day of the month.

On each day during the roll period, new notional holdings are calculated. The calculations for the old futures contracts on the Index Commodity that are leaving the Index and the new futures contracts on the Index Commodity are then calculated.

On all days that are not monthly index roll days, the notional holdings of the Index Commodity future remains constant.

The Index is re-weighted on an annual basis on the sixth Index Business Day of each November, as discussed above. However, during periods of heighted volatility or when commodity prices experience significant movements, the commodities weights within the Index may be reset or reduced based on the weight implemented at the previous annual rebalance.

The calculation of the Index is expressed as the weighted average return of the Index Commodity.

Regulation

Futures exchanges in the United States are subject to regulation under the Commodity Exchange Act by the CFTC, the governmental agency having responsibility for regulation of futures exchanges and trading on those exchanges.

The Commodity Exchange Act and the CFTC also regulate the activities of “commodity trading advisors” and “commodity pool operators” and the CFTC has adopted regulations with respect to certain of such persons’ activities. Pursuant to its authority, the CFTC requires a commodity pool operator (such as the Managing Owner) to keep accurate, current and orderly records with respect to each pool it operates. The CFTC may suspend the registration of a commodity pool operator if the CFTC finds that the operator has violated the Commodity Exchange Act or regulations thereunder and in certain other circumstances. Suspension, restriction or termination of the Managing Owner’s registration as a commodity pool operator would prevent it, until such time (if any) as such registration were to be reinstated, from managing, and might result in the termination of, the Fund. The Commodity Exchange Act gives the CFTC similar authority with respect to the activities of commodity trading advisors, such as the Managing Owner. If the registration of a managing owner as a commodity trading advisor were to be terminated, restricted or suspended, the managing owner would be unable, until such time (if any) as such registration were to be reinstated, to render trading advice to the Fund. The Fund is not registered with the CFTC in any capacity.

The Commodity Exchange Act requires all FCMs, such as the Commodity Broker, to meet and maintain specified fitness and financial requirements, to segregate customer funds from proprietary funds and account separately for all customers’ funds and positions, and to maintain specified books and records open to inspection by the staff of the CFTC.

The Commodity Exchange Act also gives the states certain powers to enforce its provisions and the regulations of the CFTC.

Shareholders are afforded certain rights for reparations under the Commodity Exchange Act. Shareholders may also be able to maintain a private right of action for certain violations of the Commodity Exchange Act. The CFTC has adopted rules implementing the reparation provisions of the Commodity Exchange Act which provide that any person may file a complaint for a reparations award with the CFTC for violation of the Commodity Exchange Act against a floor broker, FCM, introducing broker, commodity trading advisor, commodity pool operator, and their respective associated persons.

Pursuant to authority in the Commodity Exchange Act, the NFA was formed and registered with the CFTC as a “registered futures association.” At the present time, the NFA is the only non-exchange self-regulatory organization for derivatives professionals.

5

NFA members are subject to NFA standards relating to fair trade practices, market integrity, and consumer protection. As the self-regulatory body of the derivatives industry, the NFA promulgates rules governing the conduct of derivatives professionals and disciplines those professionals who do not comply with such standards. The CFTC has delegated to the NFA responsibility for the registration of commodity trading advisors, commodity pool operators, FCMs, introducing brokers, and swap dealers, among others, and their respective associated persons, as applicable, and floor brokers. The Commodity Broker and the Managing Owner are members of the NFA (the Fund is not required to become a member of the NFA).

The CFTC has no authority to regulate trading on foreign futures exchanges and markets but permits direct access to such markets from the United States with respect to foreign boards of trade that are registered as such with the CFTC.

Employees

The Fund has no employees.
